Inexpensive, fast and straightforward way to excavate, backfi ll and pour column and footing with concrete simultaneously in one day.

Safe, cuts cost, saves installation time, light weight and effi cient foundation forming system used in lieu of conventional wood forming method. (Less time, tools, materials and concrete = Less $’s)

Superior structural integrity provided through a continuous and consistent concrete pour.

No joint between Sonotube® Concrete Form and Square Foot® plastic footing form which increases strength of foundation forming system.

Creates additional project effi ciency by reducing project timelines by allowing footing and Sonotube® Concrete Form to be backfi lled prior to pouring.

Square Foot® withFeatures and Benefi ts:

COMMERCIAL

Benches, bollards, bus stops, car ports, columns, fl ag poles, house protection supports, lamps, lolly columns, sculptures, signage.

Professionally engineered, evaluated and independently tested to meet building code requirements in North America.

Wedge system snugly accommodates all types of Sonotube® concrete forms from 8, 10, 12, 14, 16, and 18” diameters.

Increases structural integrity by providing proper bearing area to carry loads imposed from various structure types above.

Square design minimizes the potential of form moving during concrete pour due to four even sides contacting soil.

Resistant to tilting, uplift, and movement cause by poor soils, high velocity winds, and frost.

Provides a slip joint between concrete footing form and earth which minimizes movement of foundation.

Eliminates cold joint, 90º angle and air pockets.

Minimum footing form thickness of 6” on all four sides to decrease lateral movement of foundation system.

Form can be positioned fl ush to pre-existing structure leaving no voids.

Suspends and holds rebar in place through unique corner perforations.

Footing form is water repellant increasing quality of foundation system.

Enclosing footing form can be achieved by nailing a piece of plywood to the fl ange of the footing.

Product designed by contractors – For contractors.

Below Grade1. Excavate hole to a depth to avoid frost penetrating under pier (Typically 5’ (1.5m) ).2. Apply construction tube to Square Foot® footing form.3. Cut off excess plastic at top of wedges to desired construction tube size.4. Attach construction tube to Square Foot® footing form with a minimum of 4 Screws.5. Place Square Foot® footing form at desired location. (On undisturbed soil or 4”-6”

(10cm-15cm) of compacted crushed stone or gravel)6. Install footing rebar if required. (See example) (Rebar installation should be approved and designed by a qualified Engineer and

meet all Building Code requirements.)7. Level/Plumb construction tube/Square Foot® footing form prior to backfilling.8. Construction tube and Square Foot® footing form combined cannot exceed/extend

36” (91cm) or more above grade/ground. (See our website for Above Ground Tech Tips)

9. Have inspected by Building Inspector as required by different municipalities.10. Backfill making sure construction tube remains level/plumbed at desired location.11. Prior to pouring concrete into construction tube invert spare Square Foot® on top

of construction tube to act as a funnel for concrete pour.12. Pour concrete.13. Install anchor bolt to accept bracket as required.

1. For any footing form project which requires the combined use of a construction tube and

footing form to exceed/extend 36” (91cm) above ground/grade when pouring concrete, the construction tube MUST be braced to prevent movement of construction tube while the concrete is curing. (Conventional methods: Strapping or 2X Materials w/Stakes; Wooden Collar; Frame with Side Braces)
